A concrete example
A farmer named Dave sells his vegetables to a food hub named "Earth Friends" which has a web platform (website), on which Dave manages his products catalog.
Now imagine that another buying group, "Eastern Farmers" also wants to distribute Dave’s products on its own web platform.
How does Eastern Farmers access Dave’s catalog? Today, the solutions are far from ideal:
1 - Dave must enter the same data on each platform, therefore loosing time and having to manage stocks and orders on different platforms.
2 - Eastern Farmers can source Earth Friend’s data and access Dave’s catalog. There are then problems of stock synchronicity (problems of errors due to delays in stock updates), data reliability and security.
The solution: interoperability. What is it ? It’s pretty awesome. To avoid complicating operations when the same product is distributed on several platforms, they must communicate effectively.
We are not talking about synchronization or data exchange, simply cross-display of data that can be hosted on any database. The data is not replicated, just displayed, from the information directly drawn from the source database.
